COMPOSITE RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 684,570, dated October 15, 1901. Application filed February 5, 1901. Serial No. 46,086. (No model.)

To all whom it may concern:

Be itknown thatI, CHARLES COPPAGE HAR- RELL, a citizen of the United States, residing atBainbridge, in the county of Decatur, State of Georgia, have invented a certain new and useful Improvement in Composite Railway- Ties, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improvement in composite railway-ties of a similar character to those shown in my Patent No. 667,698, of February 12, 1901, and my application, Serial No. 40,278, filed December 18, 1900, my object being to provide a most simple, inexpensive, and durable tie.

My invention therefore consists of the railway-tie shown in its preferable embodiment in the drawings forming part of this application and in the peculiar construction, arrangement, and combinations of parts hereinafter more particularly described and then definitely set forth by the appended claims.

In the accompanying drawings, which represent the preferable Way of carrying out my invention, Figure 1 is a top plan of a composite tie constructed in accordance with my invention with parts broken away to show the metallic framework. Fig. 2 is a side elevation also with parts broken away. Fig. 3 is a vertical cross section 011 the line as x of Fig. 1 on a larger scale. Fig. 4 is a similar section through the line y y of Fig. 2. Fig. 5 is an enlarged detail of one of the rail chairs or supports. Fig; 6 is an end view of the same. Fig. 7 is a perspective detail of the lockingwedge, and Fig. Sis a bottom plan view of the rail-chair.

Referring now to the details of the drawings by numerals, 1 represents a metallic plate extending almost the full length of the tie and which forms the main part, or, as it might be termed, the backbone, of the me tallic framework, which is adapted to support the coating or housing of cement, concrete, or analogous material. This metallic plate is perforated at a number of places, as shown at 2, and the metal punched from the plate is bent at right angles to the same, so as to form lugs or arms, as shown at 8. It will be noticed that these lugs or arms alternate -that is, every other arm projects on one side of the drawings, this framework is incased or embedded in a housing 5, of plastic material, as in my aforesaid patent and application. It will be observed that this plate or framework (as it in reality is after the lugs or arms are bent in opposite directions as described) affords a most excellent means for holding this aforesaid plastic housing 5, inasmuch as the material, besides being caught by the lugs or arms 3, enters theperforations; but to insure a still better grip between the housing and the framework I form the lugs or arms 3 with curved edges or sides, so that the lugs or arms are narrower at their centers than at their ends. My rail chair or support comprises a base 6, having at each end two downwardlydepending lugs or feet 7, perforated at 8, by means of which the lugs or feet '7 are riveted to the ends of the framework, the lugs straddling the latter, as clearly shown in the drawings. To stiffen the rail chair or support, Iform on each side of it a stiflening-rib, (shown at 8%) Extending upwardly at each end of the chair are two flanges 9, parallel with the length of the chair,and between these two sets of flanges is formed the seat 10 for the rail, or rather for the cushion 11, of compressed fiber, hard wood, or other suitable material. At each end of the chair is an upturned flange 12. The side flanges 9 are perforated, as seen at 13, and through these perforations is inserted a spike, pin, or analogous device 14. This spike or pin is preferably square and detachable, although it may be formed integral with the chair, if desired. To secure the rail in these chairs, I employ spring clamping devices 15, of the peculiar shape shown in the drawings, although, of course, this shape is not essential, as any suitable means may be substituted for these clamping-springs. In order to securely clamp these springs 15 against the foot of the rail, and thereby hold the latter in its seat, I

ICO

rail is as follows: The clam ping-spring 15 and the spike or pin 14 are placed in substantially the positions shown at the right-hand end of the enlarged detail Fig. 5, and a pinch-bar or other lever of such a width as will allow it to be inserted between the arms 17 of the wedge 16 is inserted under the spike or pin and the clamping-spring forced down until it is compressed sufficiently to hold the rail in place. The wedge is then inserted under the spike, with its arms 17 straddling the pinch-bar, and as soon as the appropriate notch 18' is under the spike the pinch-bar can be removed. Of course the clamping-spring on the other side is inserted in a like manner. It is evident that if it becomes necessary to tighten the clamping-springs, so as to compensate for any change in the spring or wear in the cushion, it isonly necessary to insert a pinch-bar, press down on the-spring, and push the wedge farther under the spike, when the clampingspring will be tightened to the desired degree.

I havedescribed and illustrated what I now consid'eras the preferable way of forming the various parts, but, except where the appended claims are explicitly limited, I do not limit my invention to theexact construction shown, but intend it to cover any variations or modifications as will naturally suggest themselves. For example, it is manifest that the arms or lugs projecting. from the plate may be made separate therefrom and riveted thereto, although on account of its cheapness the plan illustrated is much to be preferred.

What-I claim as new is-- 1. In a railway-tie, a framework comprising a substantially vertically disposed plate having a series of lugs or arms projecting laterally therefrom on each side of the plate,

the said lugs or arms projecting at short intervals for substantially the length of the having a series of lugs or arms projecting T laterally therefrom on each side of the plate, the said lugs or arms projecting at short intervals for-substantially the length of the said plate, the Whole being incased or embedded in cement whereby the series of lugs or arms on each side of the plate forma described.

3. In a. railway=tie, a framework comprising. a substantially Vertically disposed plate having perforations therein, the metal punched from the perforations forming lugs or arms projecting laterally from the said plate, there being a series of lugs or arms projecting from each side of the plate, substan tially as described. j

at. In a railway-tie, a framework coinpris- 7o ing a plate having perforations therein, the metal punched from the perforations forming lugs or arms projecting laterally from the plate alternately on opposite sides, substantially as described.

5. In a railway-tie, a framework comprising a plate having perforations therein, the metal punched from the perforations forming lugs or arms projecting laterally from the plate alternately on opposite sides, the whole being incased or embedded in cement, substantially as described.
